Yes! if you bottle up issues they might start to affect your health (random pains and aches, headaches, issues with digestion, issues with sleeping etc).
It is important to find mentors/trusted adults/trusted friends to help you talk through your concerns. Also, sometimes talking through an issue might help you find a solution, or realize that the issue is not as bad as you thought!
I do understand that it is hard to find trustworthy friends, but it is a really important investment to make, because we all need support! 🙂
